I have quite a bit of OS leftover......since OC has superceded it for me on paint. About to slap the summers back on. Probably between March - November, I normally don't use anything more harsher than CW soap.... I do use some level of APC at least 2 times between these months, just to get it down and dirty. Whaddya say. Just OC them or use up the OS.
+1, its so easy to apply, no more than a couple of minutes per wheel and you're done within 5-8 minutes that includes buffing off any residue.
